Well, by determinism here, I mean that: if one knew the position and vector/speed(I've forgotten what that second value is, its something like that. And I'm not saying its possible.) and if one knew how every particle interacted with each other, then one could know every action that would happen afterward.
What I would like to know is if anyone disputes that. Not if anyone disputes the ability to gain such knowledge, just if one had that knowledge, if they could have that result.
Because, to me, it only seems logical that if you knew how everything interacted with one another and what they were doing at any given moment, then one could, in a sense, predict the future.
